FIXING-BATH AND DEVELOPING-TRAY serrate AND enema;

Specification of Letters Patent.

Patented Sept. 7, 1920.

Application filed September 18, 1919. Serial No. 324,340.

To all whom it may concern Be it known that I, SIDNEY J. TYLER, a citizen of the United States, residing at Afton, in the county of Ottawa and State of Oklahoma, have invented certain new and useful Improvements in Fixing-Bath and Developing-Tray Supports and Rockers, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to a photograph fixing bath and developing tray support and rocker and has for its object to provide a device of this character capable of efficiently rocking the developing tray to move the developing solution from one end of the tray to the other, and at the same time cause the solution to pass over the entire surface of all the prints in the tray, as it is absolutely necessary in order to fix the prints properly that the fixing bath be in motion at the time the prints are immersed.

Another object of the invention is to provide a device of this character having novel adjusting arms, capable of supporting all sizes of trays.

A still further object of the invention is to provide a device of this character, which prevents waste of developing solution and one that can be operated manually or by any other source of power.

These objects are attained by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the developing tray support and rocker and means for rocking the same.

Fig. 2 is a perspective view of one of the adjustable arms and its connection to the rocking frame.

Fig. 3 is a detail view of the means for adjusting the rocking movement of the frame.

Referring to the drawings, 5 designates a frame having sides 6 and ends 7. The sides and" ends are each provided with extending apertured ears 8 to enable the frame to be secured to any desired support. Extending from one of the ends 7 is an ear 9, the purpose of which will be hereinafter described. Disposed on the frame 5 is a rocking frame 10 having sides 11 and ends 12. The lower surface of each of the sides 11 tapers from each end of said side to its intermediate portion, the ends of the sides 11 being the same width as the ends 12 of the frame 10,,1-so that the sides of the frame 10 form rockers. The rockers are pivoted at their intermediate portions as at 18 to the sides 6 ofthe stationary frame 5, and are intended to rock thereon. One end 12 of-the frame 10 has an extending car 14, provided with a set screw 15 adapted to engage the upper surface of the ear 9 on the frame 5, to regulate the rocking movement of the frame 10. Extending transversely of the frame 10, are tray supports 16, which not only serve as supports for the developing tray, but also brace the rocking frame 10. Movably mounted on each of the supports 16 is an adjustable arm 17 including an upwardly extending lug 18 and having a longitudinal slot 19. The arm 17 is adjustable on the support by means of a set screw 20. By means of these adjustable arms, trays of various sizes may be efficiently supported on the rocking frame.

Pivotally connected to the rocking frame 10, by means of the set screw 15 is a link 21, which is connected at its lower end to a foot pedal'22, for rocking the frame 10.

All sizes of developing tray'smay be used with this rocking frame, by simply adjusting the arms 17 to accommodate the tray to be used, and if desired, the frame 10 may be rocked either by hand, foot or by motor power, to suit the convenience of the user. The frame 5 is providedwith-guide cleats From the foregoing description, it will be readily seen that'this device overcomes the inconveniences of the unsteady hand tilting method by providing a novel and simple device which produces a' steady rocking motion, and permits the solution to pass over all of the prints in the tray in the desired manner, without causing waste. It is also a time saving device since it allows the photographer the ilse of both hands in developing while the fixing bath is being rocked With'the'foot or other motive power. What is claimed is; A device of the character described comprising a stationary supporting frame, a rocking frame coinciding with the stationary frame, the intermediate lower portion ofeach side of the rocking frame belng en-,

to the supporting frame, and arms slidably mounted on the loWer surface of each end portion'of the rocking frame, said arms be- "ing adjustable toward and away from each other beyond the ends of the rocking frame. In testimony W hereof I hereunto affix my signature. 7
